Introduction.

Cook Chill Operation.

Blast chilling is a process to reduce the temperature of cooked food by swiftly arresting the cooking process, locking in its

colour, flavour, texture and nutritional value. Department of health guidelines state that to safely blast chill food the

temperature must be reduced from +70°c to +3°c within 90 minutes.

Pre Chill

Pre chilling ensures the correct cabinet temperature in the unit before chilling commences therefore improving the chilling

performance.

Soft Chilling.

Soft chilling is the process of rapid but gentle chilling of food.

This cycle brings down the food temperature to +3°c in no more than 90 minutes without the air or food temperature going

below 0°c.

This prevents large ice crystals forming therefore maintaining the texture, consistency and appearance of food such as

vegetables, rice, pasta, custard and fruit with no dehydration or cell damage.

Hard Chilling.

Hard chilling is the process of general purpose chilling.

This cycle brings down the food temperature to +3°c in no more than 90 minutes and is ideal for chilling meat pies,

lasagne, pasta and individually portioned meals. The air temperature for this process goes down to -15°c for the first 70%

of the cycle, to extract the maximum amount of heat from the product quickly. The air temperature then increases to +3°c

for the final 30% of the time to reduce surface damage and ensure quality.

Hard Chill Max.

Hard chill max brings down the food temperature to +3°c in no more than 90 minutes and is used for chilling high density

or high fat content food such as meat joints, stews or packaged products.

The air temperature during the cycle is allowed to go down to -20°c.

After either a pre-designated time has elapsed or product temperature has been achieved, the air temperature is allowed

to rise to the ‘hold’ value with the temperature being maintained at this level indefinitely.

Surface Protection.

Removing the heat energy from food product as rapidly as possible by the combination of powerful refrigeration and

evaporator fans moving large volumes of cooled air can cause damage to the food product. The food product could have

a form of ‘Frost Burn’ caused by the fast moving air feeling cooler than the actual air temperature ‘Wind Chill Effect’. This

may lead to product discoloration, dehydration, localised freezing and spoilage of the food product.

Surface protection overcomes this by reducing the evaporation operation, and hence the air speed at pre-determined

stages in the cycle to ensure that this does not happen. This is a discreet function and happens automatically without any

intervention from the operator. To enable the surface protection; and determine at what stage it would be activated values

are set in the service operating parameters.

Longer Term Storage – ‘Hold’ Mode (Conservation)

Upon the completion of the blast chilling cycle the controller will automatically enter the ‘Hold’ mode. This will either be

because the selection set time has elapsed or the product core temperature has been achieved. When the hold period

commences an alarm will sound for a period denoted in the service operating parameters.

The controller will determine the temperature to be maintained during the hold phase based on the chilling cycle that has

been completed. If a soft or hard chill has taken place the controller will maintain an air temperature of 2°c.

The hold mode is principally intended as a temporary storage facility offering the operator flexibility until the product can

be unloaded into a longer term storage units at the correct storage temperature. On occasion this hold period may

become extended to operate overnight or to provide emergency refrigeration backup. In such instances defrosting would

automatically occur as necessary.

Model Details.

The RBC 20-60 is capable of blast chilling 60kg of product from +70°c to +3°c in 90 minutes with entry temperature up to

90°c

The cabinet is compatible with the Rational 20 rack GN 1/1 201 trolley.

Refrigerant used is R404A.

The RBC20-60 has two separate refrigeration systems comprising, two condensing units, a twin circuit condenser and a

twin circuit evaporator. (See pages 20 and 21 for assembly details and page 22 for schematic dual circuit refrigeration

layout).

The RBC20-60R has the same refrigeration systems but the condensing units are remotely sited.

Refrigerant control is by expansion valve to control the correct amount of refrigerant required to meet the demand of the

evaporator. (See page 21 for assembly detail).

The parameter ‘Capacity Enable’ is set to ‘ON’ to allow for both condensing units to be running during the chill cycle

therefore maximising the heat extraction from the product. During the ‘HOLD’ mode with the ‘Capacity Enable’ set to ‘ON’

one compressor will control the temperature throughout unless the temperature exceeds the capacity control limit.

A 1½” BSP drain outlet is fitted in to the base of the cabinet for connection to external drain.

The cabinet is delivered with the legs secured to the base of the cabinet.

Controller Technical Detail

The FCC controller is a three-piece unit made up of the Front Display and Dial Shaft Encoder, Mother Board plus

Evaporator, Food and Air temperature probes. The front display PCB and the CPU/ Switching PCB unit are

interconnected by a ribbon cable. The membrane attached to the front provides an IP rating of IP54 providing a scratch

free wipe clean finish.

The control dial is the method by which the controller is accessed for all requirements. It has three planes of movement,

clockwise, anticlockwise and inwards.

The control dial allows the operator/ engineer to move forward and backwards through various menu selections shown on

the display, and enter a desired programme. The control system will then respond appropriately either commencing the

operating cycle or allowing further configuration.

Service Information

Refer to the operating instructions on page 4 for operating instructions.

When mains electrical power is first applied to the controller it will carry out a self test function, for approximately 3

seconds, to ensure that there are good connections between the component parts. During this period the display will

show.

The information displayed in the centre of the screen refers to which of the profiles the controller is set for.

The software version relates to the software release. The number relates to the major operating changes or model

variants. The letter relates to the minor operating changes that may have been made from the original, such as parameter

settings.

On completion of the self test the controller will revert to the last chill program that was run (Pre-chill, Soft Chill, Hard Chill,

Hard Chill Max, Shock Freeze, Professional 1, Professional 2, or Professional 3). The availability of these is dependent on

how the controller has been configured. The example below shows the controller in Hard Chill.

Press and hold the dial for 5 seconds.

Firstly the display will display the information page, below left, continue pressing until the ‘SERVICE’ screen is displayed,

below right. For changes to language see page 5.

Diagnostics

Rotate the dial until you reach ‘Diagnostics’, below left, press and release the dial to highlight the component. In this

program you can test each of the major components on the machine in sequence, 1- COMPRESSOR, 2-FAN1, 3-FAN2,

4- DEFROST, 5- ALARM, 6- CCAP (Capacity Control), 7- UV-L (UV light if fitted), ESC (escape). Rotate the dial until the

relay output is highlighted, once selected press and the dial to test the relay, the relay will remain energised for as long as

it is pressed. On completion of the test you must rotate the dial until you highlight ‘ESC’ press and release the dial to

move to the next program.

Function Test

Rotate the dial until you reach ‘FOOTPRINT’, see below, press and release the dial to initiate the controller function self

test.

This allows for the engineer to test the operation of the machine without having to wait for a full program to run. The test

lasts for ten minutes and should be carried out with the cabinet / room empty. Each of the relays will be energised to

simulate the chill process. Relay 1-COMPRESSOR, Relay 2-FAN1, Relay 3-FAN2, Relay 4-DEFROST, Relay 5-ALARM,

Relay 6-CCAP (Capacity Control), and Relay 7- UV-L will all be switched on and of automatically in a pre determined

manner to simulate program operation (whether they are connected or not).

The test is based around an algorithm built into the software. Prior to starting the program it is advisable to place a probe,

in the centre of the cabinet/room, attached to an independent measuring device to check the air temperature as the air,

coil and food probes are not active during this program. The temperature achieved will depend on the model. The air

temperature should be checked 5 to 6 minutes into the program. The temperature achieved should be the minimum

temperature and can be checked against the model type found in the parameter table on page 9. (For further information

go to page 19).

Once the test is completed the display reverts to the last chill program and not to the service parameters.

Passcode.

Rotate the dial until you reach ‘PASSCODE’, below left, press and release the dial to highlight the code, below right.

Rotate the dial until you reach the code ‘131’. Once achieved press and release the dial to acknowledge.

Alarm and Warnings

In general if an alarm occurs the appropriate alarm symbol will be displayed and the alarm will sound to attract attention.

The cabinet will attempt to continue running or to finish the cycle (if safe to do so).

The distinction between an alarm and a warning is that a warning may be a non-critical occurrence such as door open or

temporary power failure. An alarm would be for a system failure such as a probe fault or high-pressure fault, which would

require positive intervention.

High pressure developing in the refrigeration system as a result of, to high food temperature,

condenser fan failure, blocked condenser, air flow restriction etc. Automatically re – sets

when the normal working pressure is achieved.

Air Probe Fault

Evaporator Probe Fault

Food Probe Fault. If more than 1 probe are enabled the probe fault would be displayed

accordingly

is open.

Ribbon cable between the power switching PCB and the display disconnected.

Foot Print Test operation

The foot print test is a method of checking the operation of the process in a reduced time period

The foot print test takes ten minutes.

The first ten seconds are used for the display test, after that the relays are energised in a simple operating pattern to

ensure each are energised. During the final ten seconds the alarm is sounded to indicate the end of the test.

The graph below shows how the relays are energised relating to time.

The air, coil and food temperature probes are disregarded (the only exception is an over temperature alarm).

Operation Summary

All relays commence Footprint test in the de-energised state.

• Relay 1 is energised after 10 seconds from start of test for 470 seconds (de-energises 480 seconds from start).

• Relay 2 is energised after 60 seconds from start of test for 30 seconds (de-energises 90 seconds from start).

• Relay 2 is energised again after 120 seconds from start of test for 300 seconds (de-energises 420 seconds from start).

• Relay 3 is energised after 90 seconds from start of test for 330 seconds (de-energises 420 seconds from start).

• Relay 3 is energised after 540 seconds from start of test for 30 seconds (de-energises 570 seconds from start).

• Relay 4 is energised after 450 seconds from start of test for 90 seconds (de-energises 540 seconds from start).

• Relay 5 is energised after 590 seconds from start of test for 10 seconds (de-energises 600 seconds from start).

• Relay 6 is energised after 360 seconds from start of test for 90 seconds (de-energises 450 seconds from start).

• Relay 7 is energised after 570 seconds from start of test for 20 seconds (de-energises 590 seconds from start).

All relays are de-energised on completion of the test.

At any point during the test pressing and holding the dial for 2 seconds can stop it. The test will be terminated and the

display will revert to the last run cycle. Upon normal completion of the test the display will revert to the last run cycle (not

the service parameters).

Probes

Air and Evaporator Probes

The air and evaporator probes are the same and are identified as T1 Air Probe and T2 Evaporator Probe. These are the

thermistor type and are fully enclosed to make it completely waterproof and resilient to temperature variation within the

limits of rapid cycling. The probe is capable of measuring temperature in excess of -30°C and 50°C with 1°K accuracy at

1°C and no more than 2°K at the upper and lower temperature ranges.

Food Probe

The food probe is inserted directly into the product that is being chilled to measure the core temperature. The resistance

values are the same as for the air and evaporator probes.
